Question

这就是我想要完成的事情：

我需要用户在登录计算机时自动运行powershell脚本，让脚本启动Elevated Powershell提示符（就像用户可以以管理员身份单击Run Powershell一样），然后让它运行一些命令在新的Powershell对象中，然后关闭新的Powershell对象。

此功能当前将在高架模式下创建并运行新的Powershell对象。

function Set-Elevation
{
   # Create a new process object that starts PowerShell
   $newProcess = New-Object System.Diagnostics.ProcessStartInfo "powershell";
   # Indicate that the process should be elevated
   $newProcess.Verb = "runas";
   # Start the new process
   [System.Diagnostics.Process]::Start($newProcess) | Out-Null
}

但是，如何让它在那里运行新命令？之后如何关闭物体？

有关语法的任何提示都将不胜感激。

您可以使用内置的Start-Process命令：

function IsAdministrator
{
    $Identity = [System.Security.Principal.WindowsIdentity]::GetCurrent()
    $Principal = New-Object System.Security.Principal.WindowsPrincipal($Identity)
    $Principal.IsInRole([System.Security.Principal.WindowsBuiltInRole]::Administrator)
}

function IsUacEnabled
{
    (Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Policies\System).EnableLua -ne 0
}

#
# Main script
#
if (!(IsAdministrator))
{
    if (IsUacEnabled)
    {
        [string[]]$argList = @('-NoProfile', '-NoExit', '-File', $MyInvocation.MyCommand.Path)
        $argList += $MyInvocation.BoundParameters.GetEnumerator() | Foreach {"-$($_.Key)", "$($_.Value)"}
        $argList += $MyInvocation.UnboundArguments
        Start-Process PowerShell.exe -Verb Runas -WorkingDirectory $pwd -ArgumentList $argList 
        return
    }
    else
    {
        # Log an error, do nothing or Start-Process -Credentials <admin_creds>
    }
}

如果您使用此自升式脚本，则可以直接在PS1中运行命令，而不会有任何麻烦。

$WID=[System.Security.Principal.WindowsIdentity]::GetCurrent();
$WIP=new-object System.Security.Principal.WindowsPrincipal($WID);
$adminRole=[System.Security.Principal.WindowsBuiltInRole]::Administrator;
If ($WIP.IsInRole($adminRole)){
}else {
  $newProcess = new-object System.Diagnostics.ProcessStartInfo 'PowerShell';
  $newProcess.Arguments = $myInvocation.MyCommand.Definition
  $newProcess.Verb = 'runas'
  [System.Diagnostics.Process]::Start($newProcess);Write-Host 'Prompting for Elevation'
  exit
}

Write-Host 'ElevatedCodeRunsHere';
Write-Host 'Press any key to continue...'
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown')

如何启动新的PowerShell实例并在其中运行命令？
